Discussions about technology are often factual, sometimes forward-looking, but rarely philosophical. But Salesforce Chairman and CEO Marc Benioff and Uber Co-founder and CEO Travis Kalanick are not typical technology leaders. In a fireside chat during Dreamforce last week, Benioff revealed that he’s a frequent Uber user, and engaged Kalanick in a conversation that went beyond Uber’s features, even going so far to say that “Life is like an Uber journey. You get on and you get off.”
